Probably because everyone doesn't have a clear upgrade available for their iPhone4 - also - you will sell on ebay and pay $30 in fees - $7 in shipping - then you will buy your phone for $200 and pay tax on $700 or $60.00... so maybe you clear $53....

I'm in the same boat. I bought iP4 on launch day with AppleCare, so I spent $368. No tax in my state. It was just swapped a month ago for home button issues so now I have an immaculate device and the warranty's good for almost another year. I kept the packaging, and I'll give my buyer the earbuds and other accessories from the new phone. If I'm lucky I'll get $450, which will almost be enough to cover an upgrade to 64GB and AppleCare+. Win!
